Be it known that I, THEODORE'J. BEREGH, Jr., a citizen of the United States, and a resident of thecity of New York, Woodhaven, borough of Queens, in the county of Queens and State of New York, have and Improved Paper-Feed- Controlling Apparatus, of which the .fol-

lowing is a full, clear, and exact description.

Among the principal objects which the present invention has 1n view are: to

avoid feeding paper in a damaged condition to printing presses; and to arrest the operation of saldpresses in the event that paper in a damaged condition is being fed thereto and prior to the damaged portion of said paper reaching the platen of said presses. a

- Drawings.

Figure 1 is a rear end view of apress having a controlling apparatus constructed in accordance with the present invention;

Fig. 2 is a vertical section taken as on the line 2-2 in Fig. 1;

Fig. 3 is a'horizontal section taken as on .the line 3-3 in Fig- 3' As shownin the accompanying drawings, the paper supplied is delivered in the shape of a roll 7, which is mounted on a spmdle 8 supported in bearings 9 of brackets 10.

he paper is fed to the printing rolls over a pipe roll 11. The pipe roll 11 is mounted in bracketed bearings 12 extending from the uprights 13 of the press frame. One of the brackets 12 is represented in the I drawings as being placed in circuit by means of a wire 14' forming part of an electric supply, and being connected with the main 15thereof. Disposed in parallel relation to the roll 11 is a rail 16 perforated to form guides -for plungers 17. The plungers 17 are disposed in position perpendicular to the axis ter switch 22 is closed. The

of the rail 16. The plungers 17 are each provided with a rounded head 18. Said plungers and the heads 18 thereof are normally pressed; by springs 19 toward the roll 11, with which they form electrical contacts unless prevented by the. interposit1on of the paper being printed.

If in the operation of the printing press and during the the roll 7, a blemish such as a hole ormarginal tear is present, one or more of the 'heads 18 in the path of said blemish makes contact .with said roll and completes an electric circuit incorporatin' a solenoid 20.

The solenoid 20 is electrically connected by a wire 21 with the rail 16 when the mascircuit incorporatingthe solenoid 20 includes a branch wire and a-resistance 26. The'resistance 26 operates to balance the current or lessen the influence thereof on the solenoid 20 when said solenoid operates to withdraw the switch from contact with the wires 34 and 35.

The branch wire 23 closes with the switch 24 to cut out the resistance 26 when the switch 30 is closed by thespring 33. The spring 33 is wrapped about the reduced end 29 of the solenoid core. 27. The core 27 and end 29 pass through a perforation in a U-shaped yoke 28, all as best seen in Fig.

1 of the drawmgs.

feed of the paper from The switch 24 is connected to the core 27 i by a rod 31. The w1re 25 is connected-to the main 32 of the supply current. The wires 34 and 35 are in circuit with any suitable form of electro-actuated stopping mechanism for a resting the operation of' the press.

From the diagram it will be seen that when, as under normal conditions, the spring 33 maintainsthe switch 30 in closed relation to the wires 34 and 35, the switch 24 is in contact with the branch wire 23. When in the courseof operation the circuit comprising the wire 21, switch 22, wire 14, roll 11 and the rail 16, is completed, the our rapidly saturate the solenoid 20. When the solenoid 20 is thussaturated, the .core 27 is drawn -into thesolenoid, and the switch 24 is forced bythe rod 31 backward to the position shown by dotted lines in Fig. 1 of the drawings, after which movement the .rent flows through the branch wire 23 to a contact with the ter the wire 23 has been cut out, the c1rcu1t if the electric connection 7. when" the paper ing Wire 23jis terminated. Af-

is still maintained through the solenoid between the roll 11 and rail 16 remains established and the 110w of current is materially reduced by passing throu h the resistance 26.

From the ore oing it will be seen that fed to=the printing machinery has a blemish such as the hole or tear in the body of the paperor on the edge thereof, one or other of the plungers 17 drops through the hole or tear and comletes the electric circuit in which the solenoid 20 is incorporated. The result of completing this circuit is to operate the stopping mechanism by operating the switch 30 to that effect.

While the mechanism above described amply provides for protecting the work against blemishes such as the hole 36, or a marginal tear such as 37 it does not provide for a defect in the paper such as results from an added thickness adhering to the paper when rolled, or a crumpled section wherein two or three thicknesses of paper become pressed together. It is to avoid such paper passing to the platen and printing mechanism that 4 I provide a band 38 and plungers 39, which down so that the the running paper; end of a screw 43 is inserted beneath collars H on the plungers 39. Springs 45 are compressed and alert to force the plungers 39 plungers are provided will contact with the rail 16 to complete the electric circuit incorporating the solenoid 20.

heads 18 with which said' means From the-foregoing it will be seen that in addition to the system and mechanism for arresting the operation of the printing press in the event of a tear or other opening in the pa er, provision is also made for arresting t e printing mechanism when a blemish such as described as a thickened section of the paper, undertakes to pass to the press. c
